About Gemini Vas Coffeae Modulare

Gemini est vas coffeae modulare quod infusionem manualem et coctionem more ollae moka in uno instrumento coniungit. Pars molendi in corpore vasis integrata est, ita ut pauciora instrumenta separata requirantur minusque spatii occupetur. Subtilitas pulveris coffeae operculum vertendo temperatur. Parte molendi deorsum pressa, exitus pulveris clauditur et modus coctionis moka incipit. Charta colatoria intra partem molendi posita, infusio manualis fieri potest. Plurimae partes ex materia plastica reciclabili factae sunt, nonnullae autem partes ex metallo constant.

Unique Properties: Gemini is a design that integrates hand-brewed coffee and a mocha pot. Users can choose different ways to make coffee according to their personal preferences. In addition, it incorporates a grinding component, allowing users to adjust the coarseness of the coffee grounds.
Dimensions & Packaging: Width100mm×Depth100mm×Height 200mm
Tags: Quick replacement, modularization, coffee brewing
Production Technology: Most coffee brewers are made of recyclable plastic, and some are made of metal. Barbecue grills are made of degradable mycelium, and grills are made of metal.
Design Challenge: Gemini's biggest challenge lies in how to combine hand-brewed coffee and steamed coffee, achieving a quick transition while still maintaining the experience. In addition, we studied the steam structure and grinding components of Mocha to integrate grinding with hand brewing and steaming coffee, reducing the need for tools. The design of the shape is also a major challenge. It is necessary to ensure the overall integrity after assembly and also take into account the aesthetic appeal of each individual unit after disassembly and assembly.
Research: We conducted a step-by-step experience and analysis of the production methods of hand-brewed and steamed coffee, and found that the current production methods are rather complicated, with a large number of tools and taking up a lot of space. In addition, we disassembled the principles of the mocha pot and grinding tools, proposed three combined methods and realized the principles through 3D printing, and conducted steaming experiments for the improved methods.
Inspiration: Gemini's inspiration comes from the experience of making coffee. There are many tools for making coffee, which take up a lot of space. Therefore, we want to design a coffee pot that combines a grinding component, retaining the experience of both hand-brewed coffee and mocha Pots, allowing users to choose different brewing methods according to their own preferences.
Project Duration: The project was launched in Beijing in May 2025 and completed in Beijing in December 2025.
Operation Flow: The user can adjust the grinding fineness by rotating the lid, press down the grinding component to block the powder drop port, and enter the brewing mode. When the filter paper is combined with the grinding component, users can make coffee by hand brewing, completing the switch between hand-brewed and steamed coffee.
